I UNITED STATES PATENT ALBERT HAYES, OF NEW YORK, 1v. Y., ASSIGNOR T0 cAnNor nnvnrornnnr CORPORATION, A CORPORATION ornnw YORK. H I I Application filed Aprils, 1916, Serial No. 88,937.

To all whom it may concern:

Be it known that I, ALBERT HAYES, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Rotary Pumps, of which the following is a description, reference being had to the accompanying drawin 's, forming a part hereof.

My invention relates to rotary devices for pumping fluids and has for its object to provide a device for this purpose which is simple and; inexpensive in construction, rapid and certain in operation, and'efiective to raise a large quantity of liquid with slight power, will be capable of use in pumping fluids without regard v to thesolid matter they may contain, which will not have any valves or other parts liable to be cut or worn away by grit or other abrasive matter and will run steadily and effectively.

With these and other-objects hereinafter explained in view, my invention consists in the construction and combination: of elements hereinafter explained and particularly pointed :out in the-claims.

Referring to the drawings,-

Figure 1 is a central vertical section of a pump embodying my invention, on line 1--1 of Fig. 2. r

Fig. 2 is a top plan View of the same.-

Fig. 8 is a horizontal section on line 33 of Fig. 2.

In the drawings 1 is a vertical shaft carried in a bearing in the end of a bracket 2 and having a pulley 3 "on its upper end arranged to be driven by a belt 4 from a motor 5 here shown as an electric motor. Theshaft 1 extends into. and issecured in a hub 6, from which radiate arms 7 to an annular rim '8. From the rim 8 extend downward bars 9 formed ri 'd with the These bars 9 are inclined slightly inward toward their lower ends and. at their lower ends are provided with an annular rim 10 from which arms 11 extend inward, the inner ends of these arms 10 being connected by a central disk-12.

The hub 3, arms-7, rim 8,:bars9, rim 10, arms 11 and disk 12 areeither formed integral, as bycasting, or are otherwise-so joined Specification of Letters Patent.

together as to form a rigid frame gradually tapering in diameter from its upper to its lower end. The hub 6 is of such ength as to hold the shaft 1 firmly so that as the shaft is rotated there will be no lateral movement of the frame.

Fitting on this frame is an inverted cohc 13 open at its lowerend. This invert/ed cone may be made of relatively thin sheet metal or other material. Ifdesired it may be made, where the device is to be used for pumping acid or other cornosive liquid, of

non-metallic materials suchas wood or glass or of metal coated with enamel or other non-corrosive material and while it is desirable to have this inverted cone made as true as possible, any irregularity of shape will be corrected in fitting it onto the frame.

The inverted cone is preferably provided at its upper end with a flange 14. Surround= ing the upper end of this inverted cone is a chamber formed by a top 15, a bottom 16, having a central opening for-the inverted cone and side walls 17, having at one an opening 18 from which ext-o, charge spout 19. The top 15 and h of thischamber are rigidly suppn. tea from bracket 2 by straps 20 and 21.

In operation as the shaft 3 is rotated, rotating with it the frame and the inverted cone, the lower end Of the cone being immersed in the liquid to be raised, the liquid is caused by centrifugal force to climb the walls of the cone and is thrown out over its upper end into the chamber surrounding it from which it flows through discharge spout 19. a p The bars 9 aid in the operation by preventing slip of the liquid relative to the inner surface of the cone.

The taper of the cone is preferably very slight, one inch to a foot being found in practice to be quite sufficient. The cone be of any length desired. Having thus described my invention, what I claim is: i
